@Log注解获取日志

环境pom依赖

主类开启AOP

@EnableAspectJAutoProxy 

Log

package com.entity;
import java.lang.annotation.*;

@Target({ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Log {
          /** 要执行的操作类型比如：add操作 **/
          public String operationType() default "";
         /** 要执行的具体操作比如：添加用户 **/
         public String operationName() default "";
 }

Controller

@GetMapping("selectAllPlusSql/{name}")
    @ResponseBody
    @Log(operationType = "selectAll", operationName = "通过MyBatis查找")
    public R selectAllPlusSql(@PathVariable("name") String name){
        List<Warehouse> list = warehouseService.selectAllPlusSql();
        TestDemo.logger.info("=selectAllPlusSql");
        return R.ok().data("warehouseList",list);
    }
